Rectangular Box Math Question = Uber Uber Hard

<p>A rectangular box is constructed from ten square tiles each of which has a perimeter of 24 centimeters. If the box is formed so that the tiles do not overlap what is the volume of the box in cubic centimeters?</p>

<p>A) 432
B) 288
C) 240
D) 216
E) 36</p>

<p>How do i approach this problem?</p>

<p>I mean i know its asking for the volume so LX W X H. So i did 6 x 6 x 6...but obviously i knew that was wrong since it was way too easy for this type of problem...</p>

<p>so can anyone explain me this</p>

<hr>

<p>also i had a another question</p>

<p>Points L, M, and N Li in a plane. If the distance between L and M is 4, and this distance between M and N is 9 which of teh following could be the distance between L and N?</p>

<p>I : 5
II: 8
III: 12</p>

<p>A) I only
B) II only
C) III only
D) I and III
E) I, II, and III</p>

<p>no clue ?</p>

<p>a= 432 cubic feet</p>

<p>This isn't worded 100% clearly, but assuming it's a closed rectangular box: You know each tile is a 6 by 6 square (for a perimeter of 24, which u got). To make a box, try to visualize this: You lay two tiles down next to each other flat on the ground for a base of 12 (the length of two boxes) by 6. then, put 2 on each side standing up to use four tiles. then put two tiles standing up to form the othof er side, and one on the remaining side (the 6 by 6) to close the box. </p>

<p>those dimensions are 12 by 6 by 6, or 432.</p>

<p>the next one is e) all 3.</p>

<p>First, if you have a straight line:</p>

<p>think of this:</p>

<p>N ---5---L---4--M</p>

<p>so in total, n is 9 from M and 5 from L</p>

<p>for the other two, think of a triangle.</p>

<p>if l and m consistute one side, for 4 and m and n for 9, using the triangle inequality theoreom-- all sides must be greater than the sum of the two, or in other words: the third side must be greater than the difference between the other two and less than their sum:</p>

<p>5<x<13. 12 and 8 are between these values, so they can be additional side lengths.</p>

<p>Wait a sec if the sides are 4 and 9 (given from the problem) and following that theorem if u add 5 to 4 = 9 which IS NOT GREATER THAN THE OTHER SIDE..ITS EQUAL TO IT..???</p>

<p>Yeah, that's what I got. You need to have 1x1x2 tiles to get a closed box, so that's 6x6x12...</p>

<p>I thought I'd provide a picture for visual aid:</p>

<p>No. The sides fo the triangle could be:
12, 4, and 9
or
8, 4, and 9.</p>

<p>exactly.. but if u use a line, not a triangle, you can get 5 as an answer using the diagram i posted</p>

<p>ali is right..i was going to post the exact same thing but she got it right</p>

<p>shivshanker where did you get these questions?</p>
